The Signal (2014) 

On a road trip, Nic and two friends are drawn to an isolated area by a computer genius. When everything suddenly goes dark, Nic regains consciousness - only to find himself in a waking nightmare.

Small indie sci-fi thriller. Lawrence Fishburne in a secondary role. You can see the reviews.  Seems interesting (with some flaws). On my list of films to watch at home, one day.
